| 摘 要： | 针对日本国鬼怒河流域小流量河流,通过对河床上附着生物膜的组成、底栖生物、细菌活性分析和AGP试验,研究了污水厂二级处理排放水对小流量河流生态的影响.研究表明,当污水厂二级处理排放水占河流流量比例较大时(研究河流所占比例为35%),同样会引发河流富营养化和影响河流水体的生态.因此,从保护水环境及其生态考虑,有必要对污水进行深度处理.

| Abstract: | In this paper,the authors studied the ecologic situation of a small flow water system which was influenced by the discharge of two-stage treated wastewater by analyzing components of biofilm,benthos,activity of bacteria on the stream bed and AGP testing.All the results demonstrate that if the discharge of two-stage treated wastewater is much(it's flow rate of 35% of river),it will result in the eutrophic situation happening and ecologic characteristics are changed.Therefore it is necessary that wastewater should be further treated after two-stage treatment to protect the water environment and ecology. |
